NGK B10EG single electrode ???
 

Are these "Racing Competition" plugs okay for a N/A 4 port 13B ? Will they work okay with DLDFIS ?

the B10egv will be too cold for your engine,

run a b8egv and you should be fine, they may still be a little cold but should be fine if your tune is good,

I agree!It wont be easy to get the engine started with plugs as cold as those.It`s prone to missfiring when not revved hard.

DLIDFIS helps with easier starting on regular rotary plugs. I've never used those B_EG(V) plugs, so I have no first hand knowledge of how they'll work.
